WHEE L-RIM.

To all when: it 'may concern.'

Be it known 1Vhat I, FRANKLIN (l. MILLER, a citizen of ihr .flnitedStates, residing .at Easton, in the eternity of Northampton and Stato ofPennsylvania, have invented certain new and useful Improvements inVh'eeh Rims; and I do hereby declare the following to be a full, clear,and exact description of the invention, suoli as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to wheelrirns carrying rubber or cushioning tiresand especially aldapted for use on the wheels of motor vehic es.

The invention relates particularly td atwo part rim, one part of whichmay be removed with the tire andanother similar part spv? stitutedtherefory Without delaying to repair a tire While on the road.

The object of the invention is to rovide a simple and practical rim of`this kinclwhich is equipped with suitable means for removably securingthe tire upon the outer section and said outer section upon the innersection.

A further object is to remove as nearly as possible all strain on thebolts which secure the removable Iiin section upon the other section.

The invention consists in the features of construction and combinationsof parts hereinafter described and more articularly pointed out in theclaims conc uding this specification.

In the accompanying drawing, illustrating.y

the preferred embodiment of my invention:

Figure 1 is a side elevation of a part of a rimA and tire, partly incentral section. Fig. 2 is an edge view of the inner rim-section alone.Fig. d is a view looking at the inner surface of the outer rini section.Fig. 4 is a crosssectional view of the rim and tire, taken through thepassage for one of the securing bolts. Fig. 5 is a cross-sectional viewof the saine parts taken through one of the lugs for securing the tirefrom Within, and Fig. 6 is a cross sectional view of the same partstaken throu h the passages for the air valve.

lRe erring more particularly to the drawing, 1 is the Wooden felly, 2 isthe inner rimsection, and 3 the outer rim section.l The tire illustratedcomprises the inner tube 4 and the outer tube 5. The rim-sections arepreferably made of sheet steel, the grooves and ribs,-hereafterdescribed, being pressed therein. The inner edge of the inner rim-Speciicaton of Letters Patent.

section 2 is turned up to forni a flange 6. In the outer surface of saidrini-seetion are formed a plurality of diagonally arranged grooves 7,preferablyT four in number and spaced equidistant apart. `Said groovesopen on the langeless edve of the section 2 and terminate against thellange 6. The inner` faceof the outer ri1n-sccticn 8 is provided Withribs or ridges 8 also arranged obliquelv and so positioned as to iii.the grooves 7. t will be noted that because the grooves and ribs areoblique, the outer rim section must be turned slightly as it is boingplaced on the inner riin section whereby it is locked against directlateral displacement. rl`he inner rini section is also provided withother diagonally arranged grooves 9 which alternate with the grooves 7around the riin. The outer riinsection is formed with perforations 10registering With said grooves 9 and through The heads of said boltsproject on the inner surface of said outer rim-section and areintroduced into the rooves 9 when said rim-sections are assemled. `Saidbolts secure lugs 12 having tapered sides Winch engage the outer tire 5from Within as shown in Fig. 5. Still .another groove 13 is formed inthe inner ri1n-section:"fdr introducing the air-valve 14 from the innertu 4 of the ,itire, said valve being passed through the telly of theWheel at, 15.

The outer rim section 3 is also provided with a flan e 15u at one edgeand a ringl is bolted to t e other edge thereof forming the seat orchannel for the tire. Either edge of the section 3 may be slip ed on theinner section irst, but it is pre erable to have the bolted ring 16 abutavainst the flange 6 so that the bolts 17 will be held in place.

The outer riin section is held upon the inner rim section by means ofbolts 18 passed through the felly and perforations 19 in the grooves 7of said inner rim secti and engaged with sockets 20 in the ribsS on saidouter rim section.

I claim:

1. The combination With the felly of a wheel, of an inner rim sectionhaving 4transverse grooves in its surface, an outer rim section havingtransverse ribs adapted to engage said grooves and provided withscrewthreaded sockets entering from the inner surfaces thereof, ineansto secure a tire upon said outer rim section and means to fasten the rimsections together comprising screwllt threaded. bolts passed throughsaid felly and section mounted on the inner rim section grooves in theinner rim seetion und engaging with the heads of smid bolts abuttingagainst seid sockets. in the outer rim section. the flange of Suid innerrim Section end means 2.
